Types of Aphasia

global aphasia location

large perisylvian lesion; often includes frontal/temporal/parietal lobes

global aphasia brain

Broca's aphasias location

inferior frontal lobe

Broca's aphasia brain

Wernicke's aphasia location

posterior portion of superior temporal gyrus

Wernicke's aphasia brain

global aphasia type

non-fluent

Broca's aphasia type

non-fluent

Wernicke's aphasia type

fluent

global aphasia primary feature

severe deficits in auditory comprehension and verbal expression

Broca's aphasia primary feature

impaired expressive language

Wernicke's aphasia primary feature

disturbed auditory comprehension

global aphasia auditory comprehension

very poor

Broca's aphasia auditory comprehension

relatively good, deficits with syntactically complex sentences

Wernicke's aphasia auditory comprehension

moderate to severely impaired

Broca's aphasia reading comprehension

variable

Wernicke's aphasia reading comprehension

moderate to severely impaired

global aphasia expressive language

limited to few spontaneous stereotypic productions; poor repetition; poor naming

Broca's aphasia expressive language

short, agrammatical sentences; slow effortful speech with articulation and phonological errors; poor repetition and poor naming; relatively spared automatic speech

Wernicke's aphasia expressive language

fluent speech; semantic paraphasias; jargon; neologisms; poor repetition; impaired naming. Sentences are usually grammatical, but often lack content

global aphasia accompanying deficits

motor deficits, apraxia, paresis, paralysis

Broca's aphasia accompanying deficits

motor deficits, apraxia, paresis, paralysis

Wernicke's aphasia accompanying deficits

sensory deficits, anosognosia
